CRMC is a material that has its melting point determined by how much pressure it is under. At 0 pressure its melting point is at 2614 degrees Celsius. For every unit of pressure increase afterwards, the melting point increases by 10 degrees Celsius. The maximum melting point at 255 pressure is 5164 degrees Celsius. CRMC's shade can be changed using the tmp2 value, the default values that are produced by placing it are 0-4.

The pressure is averaged by taking the pressure at 5 locations. It checks its current location, plus two pixels in each direction. Note that air is on a 4x4 grid, so it will be taking the pressure at 3 actual pressure grid locations.

At pressures below -30 CRMC breaks into CLST. This isn't done using a normal transition for some reason, so it can't be easily modified via Lua at the moment.

To create CRMC, CLST must be melted with QRTZ or PQRT. Then, cool it. Creating CRMC this way also allows the tmp2 value to be much higher than normal, as the CRMC can take on the tmp2 value of the QRTZ giving it a tmp2 range of 0-10.
